Abstract: 342,814. Changing signs. HAWTIN, E. V., Glenwood, Hayes Crescent, Cheam, Surrey. Nov. 21, 1929, No. 35604. [Class 3 (i). ] A number of movable mirror elements 6 are disposed behind a sign facia 2, and are adapted to be simultaneously oscillated first to a position where they receive light through the facia and reflect it thereon, and then to a position where they do not illuminate the facia nor reflect light to an observer, the elements moving relatively to one another. The facia may be in the form of a stencil or may consist of a design &c. painted &c. on the elements 6. The oscillation of the elements mav be effected by cams 20 which reciprocate racks 16 gearing with a pinion 13 on each longitudinally-pivoted element 6. Springs 19 press the rack rollers 18 in permanent contact with the cams 20, or a path-cam is provided. Alternatively the pinions 13 may gear together and the racks 16 be omitted, or arms on the elements be connected by a reciprocating bar. Sets of elements 6 arranged side-byside behind letters &c. of the sign may be actuated in any required sequence by disposing differentlyshaped cams 20 on the driving spindle 21. Lamps 30 are provided inside the sign to illuminate the facia at night, the facia being seen intermittently with the oscillation of the elements 6. Coloured transparent screens may be located in front of and behind the elements 6.

Apparatus for measuring the eccentricity of a cable core comprises an inductive probe 1 which is driven round the periphery of the cable and an alternating current generator 81 which is driven synchronously with the probe 1 to provide reference signals for two phase sensitive rectifier circuits which derive from the output of the probe signals representing the position of the core in two co-ordinate directions. As shown in Figs. 1 and 2, the cable 97 is guided by rollers 98 past a test head 114 which is rotated about the cable by a motor 80 which also drives the A.C. generator 81. The power supply for and the output signal from the rotating measuring head 114 is coupled through transformer 14, 21 to the stationary parts of the apparatus, further coupling transformers 15, 12 being provided in the head 114 to allow radial adjustment of the probe.

The signal induced in coil 33 is rectified and smoothed and fed via a calibrating potentiometer 48 and amplifying stages to two phase sensitive rectifier circuits including transistors 70-73 which are switched on in turn for half a revolution of the brobe at 90 degrees intervals to produce at terminals 78, 79 signals representing the X and Y co-ordinates of the eccentricity of the core which may be used for controlling apparatus manufacturing the cable. A full wave rectifier bridge 63 and smoothing circuit produces an output indicative of the magnitude of the eccentricity for recording. The generator 81 may have two output coils arranged to produce signals in quadrature for energizing relays 92, 86 for switching the transistors 70-73, or, as shown, the generator 81 may have a single output and a 90 degrees phase shift circuit 82, 83 may be provided. The apparatus may be used for testing the bores of plastic tubes by inserting a resilient stopper, impregnated with metal or metal oxides, into the bore.
